Genesis 15:8-10

International Standard Version

⁸ But he replied, “Lord God, how will I know that I will inherit it?”

⁹ The Lord responded, “Bring me a three-year-old cow, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon.”

¹⁰ So Abram brought him all these animals and cut each of them in half, down the middle, placing the pieces opposite each other, but he did not cut the birds in half.
